403 Conc Hard & Dust - 5L

Everbuild 403 Concrete Hardener and Dustproofer - 5L

Everbuild 403 is a concentrated silicate solution applied neat to concrete and cement surfaces. It reacts with the free lime in the concrete to harden the surface and bind loose material, leaving a residual layer that prevents further dusting and helps to reduce surface bloom. The liquid is clear and dries clear.

Two coats are brushed or sprayed on and worked well into the surface, allowing 24 hours between coats, after which the surface is hosed down with clean cold water to remove any unreacted surplus. Used for concrete floors and screeds in warehouses and garages and for external paving where a hard, dust-free surface is required.
